Actually if your running a millenia manifold or K8 manifold and have a KL-31/36 ECU your VRIS is off and you will be feeling the surging at 4000 and 4700, and then instead of the VRIS closing at 6250, they will not be closing at ~6800 and that means ur gonna be loosing power.

first you're not making any power at those rpms. It's useless if you ask me to shift that hihg IF you CAN'T make power up there.DaRepoMan73 wrote:I run my VRIS wired open and it runs fine especially when I am shifting at 8000rpms I know they are open. Besides the low rpm power loss is minimal
second. People dynoed different set-up and they did make more power with them CLOSED passed 6500rpm. Mazda made a good design if you ask me with their VRIS.
You can't make more power by closing or leaving the vris open all the time.
take a look at the bottom left image
